Oh, wait, as well the shopkeeper, witch at the hut (or was it added? I didn't checked), the shady guy (that points at said witch) at town, the dragon/demon girl of second map, the hairdesser pixie...
(without mentioning the several map encounters, the goblin kids -yes! We want pics of them too!-, or the several side characters -like the carriage guy/gals, or the many bystanders/clients at town, woods and/or cities).
I still think you could pull at least a dozen "new" pics by using other artwork (like the game over at the Inn, the drago-demon girl, etc) with minor modifications.
You could easily have your pic of the country girl leaning on a fence and the pic of the girl getting fucked by a pig as another character or simple encounter; the one of a girl being auctioned to a monster crowd could be a new bad-end or fill-in for the Pucca bad end, etc etc.
Most have pigtailed "girls", so the modifications are really easy and would take little time.
